Correction of Ionized Plasma Magnesium During Cardiopulmonary Bypass Reduces the Risk of Postoperative Cardiac Arrhythmia

Abstract

In this study the correction of ionized plasma magnesium during cardiopulmonary bypass was guided by measurements from an ion-selective electrode. This intervention resulted in a reduction in the incidence of postoperative ventricular tachycardia and an increased frequency of continuous sinus rhythm. Ion-selective electrodes constitute a convenient near-patient test, providing a basis for the targeted replacement of ionized plasma magnesium.
